s claims. (ci. 139-391) This invention relates to a process of formingsheeting for bed sheetsand the like and product thereof, and has to doparticularly with the forming of bed'sheets and similar articles ofmate-4 5 rially varying surface characteristics.

In the normal weaving of sheeting for use as bed sheets and similararticles, it has been customary to so weave the threads as to form asurface as a smooth hard surface. It is common l knowledge thatbedsheets so woven give a relatively cold feel in the winter-'time withthe result that many people use special coverings or warm` '23 Thecombing rolls may be replaced by the form? ing of the Woof threads orboth the Woof and the.' warp threads of relatively soft thread material;in any case, the result being a woven textile vfabric or continuous'form but having portions 30 ofits surface of distinctly different'characteristics. Y

In the drawing:l

Fig. 1 is a plan view, largely diagrammatic, of

`a continuous length of woven sheeting, portions 35 of the surface beingprocessedaccording to the present method and other portions retainingthe relatively hardfinished surface.

Fig. 2 is a side elevation similar to Fig. l, and also largelydiagrammatic, illustrating one man- 40 ner of roughing or combing spacedportions of the -continuously woven sheeting.

Fig. 3 is an enlarged fragmentary view of a bed sheet or similararticle, the bottom part o f the bed sheet for covering the feet beingshown at 45 the right of the dash and dot line and the central 'andupper part of the bed sheet being shown at the left of the dash and dotline.

Fig. 4 is a view similar to Fig. 3 and illustrating the forming-of thebottom part of the sheet of o warp and Woof threads .of a different typethan those usedA to form the main part of the sheet.

Figs. 5 and 6 are enlarged fragmentary views similar to-Figs 3 and 4 butillustrating the lwoof threads alone being formed of 'softer material.

55 An essential feature of the present invention is the fabricating ofspaced portions of a length of sheeting, preferably continuous sheeting,whereby to form a relatively soft surface at said spaced .fabricatedportions. Specifically, the

. process isparticularly applicable to bed sheets 5 and the forming ofthe fabricated portion for, roughly, thirty inches, and the hardfinished smooth portion for the rest of the length, or in some cases itmay form substantially half the length of the sheet. v 10 In Fig. 1 Ihave shown a continuous,` length. of

sheeting with a fabricated or processed portion as at 2 and a hardfinished standard unprocessed -portion as at 3. The continuous sheet maybe cut olf as desired and the spaced portion 2 obl5 viously. may b e ofany length desired.

In Fig. 2 I have illustrated one method of fabricating and processingthe spaced portions in a continuous length of sheeting wherein thesheeting is fed from a loom through brushing or combing rolls 4`whichcomb out and soften the hard finished surface of the sheeting to lgive asort ofannel eiect. It is obvious that the `rolls may be moved relativeto each other in timed relation'so as to process a definite length ofma- 2li terial at the points desired. In Fig. y3 I have illustra-ted anenlarged fragmentary plan view of 4a portion of the continuous sheetingshown in Figs. 1 and 2 and taken at the dividing point between theprocessedand unprocessed surfaces. 30

In Fig. 4 I have' illustrated a modification in that instead of usingroughing or combing rolls 4, a softer thread or yarn is tied to the warpand woof'threads 5 and 6; in other words, the warp and Woof threadscoming from the spools are cut and the softer, preferably heavier, yarnis tied on and fed through the loom in the regular way. When the desiredlength of the continuous sheeting has been woven with the softer yarns,they may be again cut and the standard warp and Woof -40 threads againltied on and fed through the loom.

In Fig. 5 I have demonstrated a still further modification in that thewarp threads 5'are fed through the loom in the standard way but atcertain intervals I prefer to feed through relatively soft and heavyyarns 1 to take the place of the Woof threads 6. `The feeding of thecross yarns l may terminatel at any point desired and such section mayalso be submitted to the rough- -ing or combing vrolls 4.

In Fig. 6. I have illustrated a fragmentary enlargement, somewhatsimilar to Fig. 5, in that relatively heavy woolen yarns 1 are fedcrosswise as the Woof threads in fabricating the continuous sheeting. Y,i

While the present process is particularly applicable to the fabricatingof bed sheets and the like, it will be understood that it may have otheruses such as the fabricating of babies diapers and similar articlesrequiring both a relatively smooth cold surface and a portion having arelatively soft warm" surface.

What I claim is:

1. As a new article of manufacture, a bed sheet of Woven material havingthe Warp and Woof threads of a portion thereof of standard formation topresent a relatively smooth cold feel, and the warp and Woof threads 0fa widthwise portion adjacent one end of said woven sheet having anexposed surface napped to form a relatively soft surface.

2. As a new article of manufacture, a bed sheet formed of woven materialhaving the warp and Woof threads of a portion thereof of standardunnapped formation to present a relatively smooth cold feel on bothsides of the sheet, and the warp and Woof threads of a widthwise portionadjacent one end of said woven sheet having an exposed surface onopposite sides of the sheet roughed-up to form a relatively soft nap.

3. As a new article of manufacture, a bed sheet formed of one piece ofwoven material having an area thereof extending widthwise of the sheetadjacent one end napped to provide better insulation characteristics,the remainder of the sheet being of standard formation and unnapped.

ANNETIE FRIDOLPH.
